Neither the TSX nor the OTCQX accepts responsibility for the adequacy or accuracy of this press release.

Certain of the statements made in this news release may contain forward-looking information within the meaning of applicable securities laws, including statements with respect to the build of the PSV and other seafloor production equipment, exploration plans to advance the Company's pipeline of seafloor massive sulphide systems and plans for launching the deep water seafloor resource production industry in 2018. We have made numerous assumptions about such statements, including that the Company's 2015 exploration program will proceed as planned, and assumptions relating to the funding, completion and operation of the Company's seafloor production system. Even though our management believes the assumptions made and the expectations represented by such statements are reasonable, there can be no assurance that they will prove to be accurate. Forward-looking information by its nature involves known and unknown risks, uncertainties and other factors which may cause the actual results to be materially different from any future results expressed or implied by such forward-looking information. Please refer to our most recently filed Annual Information Form in respect of material assumptions and risks related to the prospects of extracting minerals from the seafloor and other risks relating to the Company's business and plans for development of the Solwara 1 Project. The Company is assuming that the PSV and other seafloor production equipment will be built according to the Nautilus specifications and on schedule. Risks related to such arrangement include the delay to the delivery of the PSV and other seafloor production equipment and a consequent delay to the commencement of production in 2018, including delays caused by equipment failures, breakdowns, accidents or external events including the actions of contractors or other third parties. Risks related to advancing towards production in 2018 include the risk that the Company will be unable to obtain at all or on acceptable terms the remaining financing necessary to fund completion of the build and deployment of the Company's seafloor production system, and the risk that there can be no assurance that the Company's production plans will, if fully funded and implemented, successfully demonstrate that seafloor resource production is commercially viable. In addition, there is a risk that the Company's planned exploration work in the South West Pacific will not result in the expansion of the Company's prospect inventory. Except as required by law, we do not expect to update forward-looking statements and information as conditions change and you are referred to the full discussion of the Company's business contained in the Company's reports filed with the securities regulatory authorities in Canada.
